AGE-RELATED CATARACT

This study compares a new domestic trifocal lens (D615L) to the Zeiss AT LISA tri 839MP for people having cataract surgery. 90 adults with age-related cataracts will receive one of the two lenses and be followed for 6 months to measure vision at different distances. The goal is t…

This study looks at how well a new type of lens, called Clareon TruPlus, helps people see clearly at intermediate distances (like a computer screen) after cataract surgery. About 50 adults with cataracts in both eyes will get this lens and be tested 12 weeks after surgery. The go…

This study compares two types of artificial lens implants used in cataract surgery. Some patients will get a different lens in each eye, while others will get the same lens in both eyes. The goal is to see which approach gives better vision and causes fewer problems like glare, h…

This study compares two methods for teaching cataract surgery to ophthalmology residents. One group learns steps in the usual order, while the other learns easier steps first. Researchers will measure how well residents perform surgery and how often complications occur. The goal …

This study follows 61 people who previously used the REVISYON SDS 100 device for mild-to-moderate cataract. Researchers will check for side effects and measure vision changes over about 20 months. No new treatment is given; the goal is to see if the device stays safe and works we…

This pilot study looks at whether metformin, a standard diabetes medicine, gets into the lens capsule of the eye and can slow the growth of lens cells that cause cataracts. Researchers will collect blood and lens tissue from 40 people with type 2 diabetes and age-related cataract…
